8. ORTHOPHEADICS

Hypertrophic Osteoarthropathy (HO) is a still elusive paraneoplastic syndrome which is commonly related to lung cancer, showing peculiar features on bone scintigraphy. Differential diagnosis is a clinical challenge involving metastatic osteogenic disorders and oasteoarticular processes. Two female patients diagnosed with lung cancer underwent Tc-99m-MDP bone scintigraphy as part of the staging procedure. 4 hours after administration of 25 mCi of the radiopharmaceutical, images were obtained through a 2-head tomographic digital gamma camera (Helix, Elscint). HO was present in both cases, one of them also showing hyperactivity in the hemithorax where the tumor was located MDP bone scintigraphy was of paramount importance both for differential diagnosis and adequate management.
